Old Lyme — A 28-year-old registered sex offender, who is on probation, has been charged with repeatedly raping his former girlfriend earlier this month, ramming her car and choking her until she passed out. 

Anthony LaCoursiere was charged with third-degree sexual assault, first-degree sexual assault, second-degree threatening, second-degree strangulation, second-degree kidnapping and first-degree unlawful restraint. He was arraigned Monday in New London Superior Court, where Judge Hunchu Kwak kept his bond at $500,000 and continued the case to Feb. 5.

The warrant for LaCoursiere's arrest details brutal and repeated attacks against his former girlfriend of about five years.

The alleged assaults took place at his home and in his car between Jan. 1 and 2 in Old Lyme. State Police determined LaCoursiere had physically and sexually assaulted his one-time girlfriend, a 21-year-old woman, multiple times. He was placed under arrest at his residence at 314 Canty Lane.

When police investigated a Jan. 4 incident, in which they said LaCoursiere drove to the victim's home in East Haddam and rammed her vehicle, the woman also told them about the alleged sexual assaults on Jan. 1 and 2.

The warrant states the woman arrived at LaCoursiere's residence on Jan. 1 during the morning to discuss their relationship and how she had slept with another male within the last few days. The woman then said LaCoursiere began punching her in the stomach, face, legs, groin, and also urinated on her several times. Police said they took photos of the victim's injuries, and she provided state police with her urine-soaked clothes.

The woman said she left LaCoursiere's home on Jan. 2 and returned later that day. They argued, and she left to go to her parents' house in Old Lyme.

On Jan. 9, the woman offered more details about the incident to an Old Lyme police officer. She described a variety of physically and sexually violent acts allegedly carried out by LaCoursiere. At one point, the victim told police, he choked her until she blacked out.

On New Year's Day, the warrant states LaCoursiere physically, verbally and sexually assaulted the victim for hours, then took her to a party before bringing her back to his home in Old Lyme. When they returned, he continued to assault the woman until they fell asleep. He gave the victim her car keys on the morning of Jan. 2, and she left.

On Jan. 10, the woman's mother told police her daughter started dating LaCoursiere when she was 17. She also told investigators that last year, the woman suffered a broken sternum. She initially told her mother she was injured by a horse, although she eventually said on Jan. 5 that LaCoursiere had caused the injury.

On Jan. 10, the woman's roommate told police they'd seen LaCoursiere verbally and physically abuse her in the past. 

LaCoursiere served four years and four months in prison after being found guilty of sexually assaulting a juvenile between the ages of 13-15 in 2009 in New London. He was arrested in 2011 and sentenced in 2012 to 10 years in prison, suspended after 52 months, and 10 years of probation. He was found guilty of violation of probation in 2016.

After the Jan. 4 incident in which police said he chased the victim in his car, he was charged with first-degree reckless endangerment, second-degree criminal mischief, second-degree breach of peace and second-degree unlawful restraint. He posted a $9,500 cash bond and was released.

Last Thursday, LaCoursiere was charged with violation of probation for the hit-and-run incident on Jan. 9. He posted a $75,000 bond and was released.

In 2011, LaCoursiere, then 19, was found guilty of third-degree assault and carrying a dangerous weapon after stabbing a 17-year-old male. He was sentenced to 18 months in prison.
